Construction oversight is a critical element of a successful project. Princeton Hydro's engineers prefer to design projects that include construction oversight, so we can ensure adherence to our design or modify the construction approach to adapt to actual field conditions. Ecological restoration work requires a level of detail and ecological understanding beyond even the best machine operator's abilities. By providing construction oversight, we can be certain a project is our built to our firm's high standards.

In conjunction to our on-site oversight services, our team of engineers and scientists provide unparalleled services to ensure compliance with engineering plans, specifications and recommendations as a result of subsurface investigations. Our construction engineers provide review of shop drawings, progress surveys, and payment requests as well as overall construction administration services.

We also provide in-house laboratory testing services. Our staff is certified by the Nuclear Regulatory Commission in the use of nuclear construction materials density testing gauges and the American Concrete Institute (ACI) for the purposes of collection, storage and testing of concrete samples.
